FUMIGATOR OR DISINFECTING-LAMP.

Application mea March 17, 1915.

To all whom t may concern:

Be it known that T HENRY R. OCHs, a citizen of the United btates, and a resident of `Westport, in the county of Fairfield, State of Connecticut, have invented certain new and useful improvements in Fumigators or Disinfecting-Lamps, of which the following is a specification, reference being had to the drawings referred to, which are made a part hereof.

My invention relates to the class of fumigators known quite generally as fumigating candles, and among its objects are to produce such a fumigator extremely simple, compact and cheap, with, however, perfect reliability and safety in use in the hands of ordinary laymen.

Fumigating apparatus is made in various sizes, but the expensive or large apparatus is operated outside the chamber to be treated, so that the apparatus can be under the direct and constant care of some one. On the other hand, fumigating candles or lamps are placed in the room to be disinfected, and when once started the room is closed and sealed, andthe lamp inaccessible for any adjustment, and its proper action can only be determined after the time allowed for fumigation is over. Therefore, if not certain of action and reliable, the failure cannot be determined until after the lapse of time, and all the work incident to fumigation must be repeated if the lamp has failed. Likewise the danger of setting lire, or damage liable through emanation of soot, will happen without detection luntil the period of fumigation is over, with resultant serious consequences.

The small fumigator or disinfector is well known, but those heretofore on the market have been unreliable and dangerous in many respects. For instance, those with a wick are frequently found after use to have caused damage by soot, or the wick has become displaced, giving such a large flame as to reach and destroy the disinfecting gas,-or the liame has gone out,-or the fire or scorching of articles adjacent to the candle have resulted in damage and sometimes conflagrations.

Among the objects of my invention is the production of a lamp overcoming the various defects recited, and embodying other advantages as will hereinafter more particularly appear.

Specification of Letters Patent.

serial No. 15,102.

In the particular form of my invention herein described and shown in the accompanymg drawings: Figure l is a side elevation. Fig. 2 is a perspective view of the frame. Fig. 3 is a sectional elevation.

In the particular form illustrated, A is a frame consisting of a single piece of wire bent to form a stand and suitably support all parts; B is a metal container for the disinfectant, which also serves as a boiler; C `is a. metal box containing the solidified alcohol used as the fuel; D is a shallow pan surrounding the fuel box C.

rThe disinfectant container B,hasa removable cover B, permitting it to be readil filled with formaldehyde until used; B is a lateral corrugation to position the box in the support; and 13 is a generally curved or rounded bottom. The fuel box C has a pressed metal top C', and a central opening with a friction cap C, the solidilied alcohol being inserted through the openmg and the opening made of a predetermined siZe which will afford a flame of exactly the right size. rThe pan D is open on the top and has a beaded top edge to engage its support.

The frame A has a substantially circular top a, adapted to snugly fit the box B and engage the lateral corrugation B", thereby holding it in the predetermined position with relation to the other parts. rThe frame bends downward, having the upright support Z9, which at its bottom may be slightly kinked, and the continuation of the wire is bent into a circular support or ring c, adapted to engage the box C and hold it the predetermined distance under the box B, and particularly to hold it firmly in a central position. The continuation of the frame wire takes a bend cl, and then merges into the ring e a little below the plane of the ring c, but at a greater diameter, and adapted to encircle the pan D, the twist cl being so fashioned as to clear the beaded edge of the pan D. The wire frame continuation in the up right f, which, at its bottom merges into the ring g, forms the base for the stand.

Tt will thus be seen that the formaldehyde may be packed in the box B, sealed, and will preserve the disinfectant, until used, while the box may thereafter be most readily inserted into the ring a. The box C can be separately lled with its fuel, and the pan D first inserted into its supporting ring e, and thereafter the fuel box C readily slipped into its encircling ring c. Thus all parts may be made separately and filled separately, affording greatest economy in these operations, and thereafter all may be slipped quickly, without the slightest trouble, into the frame A, and will then have their proper relative positions to insure the proper functioning of the fumigating candle when used.

In addition to the economy in manufacture and assembly, the construction is compact and not liable to derangement, while the base g supports all parts the desired distance above the object on which the fumigating candle is placed.

The solidified fuel being carried in a sealed metal box is entirely safe for transportation, and by accurately proportioning the orifice in the top of the box, and having the box the right distance below the formaldehyde can, the proper size of flame is insured, which will heat the formaldehyde and gasify it at a proper rate, without any chance of the flame spreading around the formaldehyde can, thereby avoiding the chance of the flame coming into contact with the formaldehyde gases emanating from the top of the can. As the space around the flame is entirely free, there is no obstruction which would cause sooting of the flame, which is also further insured by the rounded bottom on the can B.

As shown in Fig. 2, the water placed in the pan D encircles the fuel box C, thereby preventing the fuel box from coming into contact with objects which might be scorched or set lire to. ln addition the currents of air feeding the flame to cause combustion, pass radially inward from around the device as indicated by arrows, and pass over the annular water space, while the currents so set up, as well as the products of combustion of the flame would pass upward along the sides of the box B, and in this manner vapor rising from the water in the pan D, would be carried up along the sides of the can B, as indicated by stippling, which brings the water vapor into contact with the formaldehyde gas above the can B. This would not be possible if there were any lateral projections on the can B, or in the frame, but the construction lends itself most admirably to insure a certain amount of vapor mingling with the formaldehyde gas, which therefore increases its efficiency in fumigation.

It will be seen that my improved fumi-- gating candle is extremely cheap to manufacture, the separate parts may be assembled with the utmost simplicity, or parts may be replaced for defective ones in course of manufacture, or otherwise, without the slightest trouble; the disinfectant, as well as the fuel are preserved against deterioration or danger in hermetically sealed metall cases,

which" may be'opened by any one without a special device; while there is no necessity for any adjustment of `flame or parts,-but the safe andV reliable. operation of the candle is insured even in the hands of the most inexperienced layman, and its use involves nothing more than the application of a match after removal of the caps and theinsertion of a small amount of water Vin the bottom pan, if desired. rlhe proportion of parts is such that the amount of fuel is just sufficient to completely gasify the formaldehyde, and whenthe operation is completed the parts of the candle are simultaneously exhausted without any danger whatsoever from flame or other cause. rlhe candle may then be thrown away, as the construction is so cheap as to make it unwarrantable to reship or renew parts for reuse; but if desired extra packed cans and fuel boxes may be supplied.

In addition to the many advantages that will appear from the above, it may be noted that formaldehyde for devices of this sort, has not heretofore been packed in all-metal cans with friction caps or other suitable means to positively avoid deterioration; nor has solidified alcohol been used in this manner for this purpose, with its peculiar advantages already recited.

Various changes may be made in size or dimensions and in other respects, without eparting from the spirit of my invention,
